Lapacho, also known as Pau d’Arco, is an amazing medicinal plant from the rainforests of South America. Used for centuries by the indigenous population, this plant has also attracted attention in the West in recent decades. This article will take a closer look at its discovery, its various forms of application, dosages and health benefits, as well as possible side effects and recommendations for taking it.

Discovery and history

The discovery of the Lapacho tree goes back to the indigenous peoples of the Amazon region, who used the bark of the tree to treat various ailments. Lapacho, known botanically as Tabebuia avellanedae, was traditionally prepared as a tea and used to strengthen the immune system and treat infections. The first scientific study was conducted in the 19th century, when European researchers began to document and analyze the plant medicine of the indigenous peoples.

Lapacho: dosage and forms of administration

It can be taken in different forms. The most common form is lapacho tea, which is made from the inner bark of the tree. The bark is dried and sold in small pieces or as a powder. To prepare the tea, about one tablespoon of bark is boiled in one liter of water for 5 to 15 minutes and then allowed to steep for 15 to 20 minutes.

In addition to tea, there are also Lapacho capsules and tablets that contain standardized extracts. These are particularly suitable for people who do not like the taste of tea. The recommended dosage varies depending on the product and concentration, but is usually between 500 and 1000 milligrams per day.

Lapacho: healing properties

It has an impressive list of health-promoting properties and is used to treat a wide range of illnesses:

Infections and inflammations

Lapacho contains naphthoquinones, in particular lapachol and beta-lapachone, which have strong antibacterial, antiviral and antiparasitic properties. These compounds inhibit the growth of bacteria, viruses and parasites, making Lapacho an effective remedy for infections. It has been shown to be particularly helpful for respiratory, skin and gastrointestinal infections.

Prevention and treatment of cancer

Some studies have shown that lapacho can inhibit the growth of cancer cells. The antioxidant properties of the plant protect cells from damage by free radicals and can thus help to prevent cancer. In addition, it is often used in naturopathy to strengthen the immune system and alleviate side effects, in addition to conventional cancer therapy.

Diabetes and blood sugar control

Lapacho can also help to regulate blood sugar levels. Studies have shown that the ingredients can improve insulin sensitivity and lower blood sugar levels. This makes the plant particularly interesting for people with diabetes or prediabetes.

Digestive complaints

Thanks to its anti-inflammatory and antimicrobial properties, Lapacho can also help with digestive problems such as irritable bowel syndrome, gastritis and other gastrointestinal complaints. The tea soothes the mucous membranes and promotes a healthy intestinal flora.

Effect on the body

The effect of Lapacho on the body is manifold. The active ingredients contained in it stimulate the immune system, promote detoxification of the body and have an anti-inflammatory effect. This can lead to a general improvement in well-being and increased resistance to disease.

It also has an antioxidant effect, i.e. it protects cells from oxidative stress. This is particularly important for preventing chronic diseases and slowing down the ageing process.

Lapacho: recommended intake and contraindications

When should Lapacho be used?

It can be taken as a preventive measure to strengthen the immune system, especially during times of increased susceptibility to infection, such as in winter. It can also be useful for existing conditions such as infections, inflammations or digestive problems.

Who should avoid Lapacho?

Although it offers many health benefits, there are also contraindications. Pregnant and breastfeeding women are advised not to take it, as there are not enough studies on its safety. People with severe kidney or liver disease should also only take it after consulting their doctor. People who take blood-thinning medication should also be careful, as Lapacho can affect blood clotting.

Additional dietary supplements and medicinal plants

Lapacho can be supplemented with other dietary supplements and medicinal plants to enhance its effects. Combining it with probiotics to support intestinal health, vitamin C to strengthen the immune system and zinc to promote wound healing is particularly useful. Medicinal plants such as echinacea, ginger and turmeric can also have a synergistic effect and support its anti-inflammatory properties.

Lapacho: side effects and overdose

Side effects

Taking it is generally safe, but it can cause side effects such as nausea, diarrhea or allergic reactions in some people. These symptoms are more likely to occur in sensitive individuals or at high doses.


Overdosing can lead to serious health problems, including impaired kidney and liver function. It is therefore important not to exceed the recommended dosage and to consult a doctor if in doubt.

Naturopathy and Lapacho

In naturopathy, it is valued as a versatile remedy. It is used in phytotherapy and often in combination with other medicinal plants to achieve optimal results. The bark of the lapacho tree is traditionally used as a tea, tincture or in capsule form to release its healing properties.


Lapacho is a fascinating plant with a wide range of health-promoting properties. Its antimicrobial, anti-inflammatory and antioxidant properties make it a valuable component of natural medicine. When used correctly, it can strengthen the immune system, fight infections and contribute to general health. However, it is important to follow the recommended dosages and to consult a doctor if in doubt.
